Human activities and weather are interrelated both directly and indirectly. Weather has an impact on various activities, including agriculture. This phenomenon is interesting because humans have no control over the weather. Weather information is very important for decisionmaking in agriculture. Weather information can actually be seen on various websites or weather information provider institutions, but the information presented usually covers a large area so that readings can occur that are not in accordance with local araea. The purpose of designing a weather parameter data acquisition system to provide information from several weather parameters at agricultural locations in Watang Suppa Village. The method in this study uses Research and Development by designing a system using Esp32 as the main control to integrate several sensors, namely DHT21 to measure air temperature and humidity, BH1750 to measure raindrop light intensity to determine rain conditions and Real Time Clock (RTC) to display time. The data will be stored in the data logger and then isplayed on the LCD. From the research results, the design of the weather parameter data acquisition system works well, at the temperature reading the accuracy level between the dht21 sensor and the measuring instrument is 97.92% while the BMKG data is 93.43%, at the humidity reading the accuracy level between the sensor and the measuring instrument is 94.03% while the BMKG data is 84.75%, As for the light intensity sensor, the accuracy level of the sensor with the measuring instrument is 96.56%.
